eclipse+jlink在RAM中调试代码
使用eclipse+jlink下载到flash中调试stm32g0已经可以，现在想把代码放到RAM中调试，改了3个地方，但失败了，请问有研究过的小伙伴吗？网上资料都查不到1、定义VECT_TAB_SRAM宏定义
2、修改脚本文件，代码都映射到RAM中
3、修改Debug配置选项
修改的脚本文件

帮顶，没在eclipse上设置过RAM调试。 eric2013 发表于 2023-12-4 15:44

如果只把某个函数放到RAM中运行呢？硬汉有接触过吗？我改了也不成功

感谢分享，能把函数放到RAM里执行了，还是想实现整个代码放到RAM里执行，MDK就可以，eclipse不知道少了哪步 我的步骤是正确的，犯了低级错误，工程选择核的时候选了M3，改成M0就可以了
